3 Claims.

This invention relates to window screens and has for the primary object,the provision of a screen construction which will be extremely durable,and may be economically manufactured and sold in a knock-down condition,easily assembled and made to fit window frames of different sizes by alayman.

Another object of this invention is the provision of a metallic framewherein the rails thereof may be stamped from sheet metal and each railincludes companion sections ribbed and grooved to interlock whenassembled and provide means of clamping the foraminous material of thescreen thereto as well as providing rigidity to the screen frame.

A further object of this invention is the provision of corner bracketsinterlocking with the sections of the rails for securing the sections ofthe rails to the frame formation and cooperating with the rails inproviding a frame which will have a maximum amount of 'rigidity toprevent distortion or sagging out of shape of the frame when in use.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists of certain novel featuresof construction, combination and arrangement of parts as will be morefully hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing in which' Figure 1 isa front elevation illustrating a screen constructed in accordance withmy invention,

Figure 2 is a fragmentary transverse sectional view taken on the line 22of Figure 1,

Figure 3 is a fragmentary perspective view illustrating one of thesections of one of the rails of the screen frame,

Figure 4 is a perspective view illustrating one of the corner brackets.

Referring in detail to the drawing, the numeral 5 indicates the frameand 6 the foraminous material. The frame 5 includes longitudinal andvertical rails and corner brackets 1. Each rail includes companionsections 8 and each section and are brought together the foraminousmaterial will be forced into the grooves by the ribs of one sectionfitting in the grooves of the companion section. Thus when the sectionsare secured toeach bracket is preferably stamped from sheet frame,

gether by the fasteners the foraminous material is firmly anchored inthe frame 5. The grooves I0 of the corner brackets receive the ribs ofthe rails so that the flanges of the corner brackets abut the flanges ofthe rails and are arranged inwardly thereof.

Thus it will be seen that when the rails and brackets are assembled inframe formation and secured by the fasteners a very rigid and durableframe is provided, one which will not sag or become out of shape andalso will not permit the foraminous material to become loose. If theframe is of the sliding type in the window frame the flanges of therails will provide comparatively broad surfaces to engage with thewindow frame and permit the screen frame to slide freely and is of theswinging type the flanges of the rails may be employed for attaching thehinges to the screen Further it will be seen that a screen of theconstruction described and shown in the drawing can be economicallymanufactured in that all the elements of the frame may be formed fromsheet metal and then cut by any layman to assemble the frame of adesired size. It is to be understood that the frame 5 may be used inconjunction with foraminous material either of metallic or plasticnature.

While I have shown and described the preferred embodiment of myinvention, it is to be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is:

1. In a screen, a frame including vertical and longitudinal rails andcorner brackets bracing said rails at the corners of the frame, saidrails each including companion sections, foraminous material closing theframe and extending between and gripped by said sections, and means forsecuring the companion sections together and the brackets to the rails,and flanges formed on the outer edges of each section of the rails andextending outwardly from the respective sides of the frame to provideabutments at the corners and at each side of the frame for selectivelypositioning the corner brackets at either or both sides of the frame.

2. In a screen, a frame including vertical and longitudinal rails andcorner brackets for bracin said rails at the corners of the frame, saidrails each including companion sections, said sections and bracketsstruck from sheet metal material and each provided with ribs defininggrooves, forfrom the respective sides of the frame to provide abutmentsat the corners and at each side of the frame for selectively positioningthe corner brackets at either or both sides of the frame.

3. In a screen, a frame including vertical and longitudinal rails andcorner brackets for bracing said rails at the corners of the frame, saidrails each including companion sections, said sections and bracketsstruck from sheet metal material and each provided with ribs defininggrooves, foraminous material closing the frame and extending between thesections of the rails and forced into the grooves by the ribs, fastenerssecuring the companion sections together and the brackets to the rails,a flange formed on the outer edge of each section and extending at rightangles thereto, and flanges formed at right angles on the outer edges ofthe corner bracket and positioned against the flanges of adjoiningsections at either or both sides of the frame when the sections areassembled in frame formation,
